For one, the battery door is completely different, is it doesn't cover the entire back of the phone. Also, notice the missing 4G LTE logo and the kickstand, which replaces the words "With Google" with "With HTC Sense".

Why would the two images be different? Well, perhaps the images that Droid Life got were from an earlier render, or perhaps this dummy is for the international version (the image was title "incredible dummy" for what it's worth). Either way, we'll find out on Thursday.
